Re: PCM Tuning Progam for NorthStar V8's?

I have been talking with them and I understand why everyone won't mess with it. It would really take a pretty good overhaul of the existing program to make it work right. They do it now, but have to apply some manual processes to the .bin before they can write it back into the PCM.

Looks like Tunercat OBD2 (now called Jet Dynamic Spectrum Tuner) IS working on it, if anyone would mess with it, they would.

From what I gather, keep watching, support might be closer than you think. Westers CAN do it now, but the PCM must be shipped to them for it (I agree on the reason)

Re: PCM Tuning Progam for NorthStar V8's?

They do, but not that you can do yourself. Again, there is a GOOD reason for it, it is how the PCM is setup and how the flash is setup and saved. There is no interface out there for it, so much must be done manually in a text editor editing direct addresses in the memory blocks.

Send an email to mailto:nwester@eidnet.org and ask questions about what they can/can't do.

We should have a major amount for Cadillac done by April end...We've got to
satisfy our V6 clients first...

this is what westers told me last week so i quess they are working on it and might get it done atleast there will be something that can be done they also said you can with a lp yourself
it would be nice if tunercat will do it they have a messge board that a few people use start another thread let them know

Re: PCM Tuning Progam for NorthStar V8's?

Not quite sure what sent them over the edge, but I guess that is how they handle it.... Oh well.

My guess it would take $2-$5K to do the work to break the code and get a solid definition file. Salary, PCM's, technican work to pull parts and fix things, and software guys to do the work.

How long to break even and then how long to be profitable?

You're kidding, right?

First, HP Tuners isn't ticked at Cadillac Owners, they're ticked at CadillacETC1997. He's impatient and has a tendency to rub people the wrong way.

That said, they shouldn't deny us this for something he said.

As for costs, you're talking a couple years salary for a couple of programmers specialized in reverse engineering. Lets just round it off to $100k. How many of their tuning packages will they have to sell to recoup that? How much more can they make by hacking some diesel truck computer instead?

Re: PCM Tuning Progam for NorthStar V8's?

rofl
those guys were fu**in idiots...
all i kept doing was asking for updates they got all pissy and i told them they couldnt do it and thats why they wouldnt
so they cried like a bunch of babys thus proving my point they couldnt do it, easier to blame a consumer than admit their failure, they werent gonna hack it, in 2 months they never responded with any information...

Re: PCM Tuning Progam for NorthStar V8's?

I am close to having tuning 96 - 03 Northstar PCMs tunable. I have some great 96 To 99 programs. I have some great programs for 00 to 03. )4 and 05 have a different PCM and I have not researched them. I have a great 00 vin 9 program that is set up for no converters, open speed limiter and all OBD II test marked as passed. I have some great 03 programs they are very nice, but I am not finished. I also need to set up a northstar with a manual trans. In the next two weeks I hope to get a lot done. as you all know it may be two months. I currently have a Northstar that runs a 99 PCM vin Y and it runs 0 to 60 in 4.2, 0 to 100 in 9.6 sec and the quarter in 13.4.

Re: PCM Tuning Progam for NorthStar V8's?

This is not a joke I am a Cadillac tech with a lot of friends at GM I have found a way. I am waiting for some more parts for my PC.
How much money do you all have.
The programs I have that are complete, but Locked. I am looking at a way to open them up to you. I can do some custom calibrations as of today. VIN 9s are very easy.

Re: PCM Tuning Progam for NorthStar V8's?

What is it that you need to have re-calibrated?
I can do a lot currently.
I would need to know your emissions testing requirements. I can remove the speed-limiters and alter several other items.
I can set it to run without post O2's. Leaded fuels. The list goes on.
VIN 9s are the easiest, But I have completed several VIN Y Performance upgrades on 2000 to 2003. I have done several 97 to 99 cars.
The parts I ordered for my PC will not work. It is the second one I purchased for my PC that is not compatible.
I will fix my laptop and just use it.
